The trial of Michelle Troconis, the woman accused of helping boyfriend Fotis Dulos cover up the suspected murder of his ex-wife, began Thursday with testimony from investigating cops — as her family swore outside the courtroom that she was innocent.

Two officers from the wealthy Connecticut enclave of New Canaan testified in Stamford Superior Court that they found what appeared to be blood on the black Range Rover found in victim Jennifer Dulos’ garage when they looked into her May 24, 2019, disappearance.

“It looks like it’s been scraped or rubbed from the vehicle,” Lt. Aaron Latourette said on bodycam footage presented in court. “Down the side of the vehicle, there’s blood. There’s some on the tire, too! It’s a lot of blood.”

As the video played, Dulos’ elderly mother, Gloria Farber, sat in the front row flanked by Jennifer’s sister, Melissa, and Carrie Luft, Jennifer’s closest friend.

Both wore purple — Jennifer’s favorite color — and nearly the entire right side of the courtroom wore purple pins to express their support.

When the footage showed cops going through Jennifer Dulos’ things — including a notepad with handwritten missives from her late daughter — the mask-clad Farber leaned forward and clutched her cane with a white-knuckle grip.

“Gloria knows today is the first day of a very long process,” Luft said afterward.

A six-member jury will decide the sensational case — which has drawn attention from across the globe — and determine if Troconis, 49, conspired with her boyfriend, Fotis Dulos, to cloak Jennifer’s murder.

She vanished after dropping the couple’s five kids off at school. Her body was never found.

And the main suspect — Fotis — died by suicide shortly after being charged with capital murder, murder and kidnapping in January 2020.

A judge officially declared Dulos dead in October 2023.

Police have said Fotis Dulos waited for Jennifer to return home that morning, then attacked her in the garage and tried to clean up the scene.

He then drove off with her body in another SUV, which was later found abandoned at a local park.

Troconis, who has pleaded not guilty to charges of conspiracy to commit murder, evidence tampering and hindering prosecution, claims she doesn’t know what happened to Dulos — or where her body might be hidden.

And she insists that she didn’t know Fotis Dulos was doing anything wrong when she watched him toss black garbage bags filled with Jennifer’s clothes and four 3-foot-long zip ties stained with Jennifer’s blood across Hartford, Conn., on the night of his wife’s disappearance.

“It appears the Zip Ties were used to secure and incapacitate Jennifer Dulos for some time period, during which her blood transferred onto the ties,” court documents stated in 2020.

“It is reasonable that Jennifer Dulos was alive at the time the Zip Ties were attached to restrain her movements and prevent her escape.”

“It’s been 4 1/2 years since I was wrongly accused,” Troconis wrote in an October X post. “I have faith in Justice and the jury system.”

During a break in the proceedings Thursday, the Troconis family told gathered media that they believed Michelle was innocent.

“We stand together as a family, ’cause that’s what we are, we’re in unity to support my sister,” Claudia Troconis said.

“She’s a mother, a daughter, a sister, an amazing mother, and just an amazing human being,” she continued. “And we know that the truth will prevail and justice will be done because she is innocent … this has been unfair for the past four-and-a-half years.”

There were no opening statements Thursday – they’re not required under Connecticut law.

Jennifer Dulos belonged to a wealthy New York family — her father, the late Hilliard Farber, founded a brokerage firm.

When Dulos disappeared, she was engaged in a nasty divorce and custody battle with her estranged husband.

Fotis Dulos died in a Bronx hospital on Jan. 30, days after he attempted to take his own life while out of jail on $6 million bail, and a day before he was scheduled to attend another bail hearing.

He proclaimed that he was innocent and had not killed Dulos in his suicide note left at his Farmington, Conn., home.

Farber has been caring for her grandchildren, who are now between 13 and 17, since her daughter’s disappearance.

Just before the trial, Luft released a statement on behalf of Duolos’ family and friends that said they have “waited patiently, understanding that the justice process moves slowly and deliberatively, especially given the disruption of a global pandemic.”

“As this trial begins, it is crucial to remember who is at the center: Jennifer, whose five children have lost their mother and, as an eventuality, both parents,” the statement said. 

“Jennifer’s family and loved ones have lost a loving daughter, sister, cousin, and lifelong friend,” it continued. “We do not seek closure, as nothing can bring Jennifer back. Our hope is that this trial provides for accountability and answers.”

The trial is expected to last about six weeks.

Fotis Dulos’ friend and lawyer, Kent Mawhinney, also was charged with conspiracy to commit murder.

He has pleaded not guilty and awaits trial. He also is accused of helping to cover up the killing after the fact.
